The radiation you receive from airport body scanners is less than what you get on the flight. It's safe for everyone to use, ...

Australia's SpIRIT nanosatellite is the first space telescope funded by the Australian Space Agency to carry a scientific ...

Former Penn physicist Arthur Goodspeed is the accidental creator of the X-ray, and his images have since been donated to the University.

It's a celestial event that has astronomers both excited and puzzled. Dan Smith has the story of how a gamma-ray burst across ...

A lead halide material can detect and image single gamma-ray photons with both high-spatial and high-energy resolution ...

SpIRIT, Australia’s first astronomy nanosatellite has completed its commissioning phase. This satellite will detect gamma-ray ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

High energy scans or the body looking for tumors or infections could be greatly improved by adopting perovskite detectors instead of the fragile or low-resolution options currently in use, a new study ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

Breakthrough perovskite crystal camera delivers sharper, faster, safer nuclear medicine scans at lower cost—promising shorter scan times, reduced radiation, and wider access to advanced diagnostics ...

Scientists have created a perovskite-based gamma-ray detector that surpasses traditional nuclear medicine imaging technology. The device delivers sharper, faster, and safer scans at a fraction of the ...
